I'm having a problem with displaying objects in high quality shading after I installed a new video card. The card is an ATi X1950 Pro 256 AGP and is causing objects in maya to have all this staticy blackness dance around. It can be remedied if I turn off High Quality shading but I need that at the moment to view some normal maps and then render them in hardware (which have the same artifacts). I've also updated to the latest driver which had the same problems. Please someone help me :\

Maya 7.0
P4 2.8Ghz
1Gig ram
X1950 Pro AGP

Thanx
